Tom Regan — B2B GTM Strategist & Founder of Artemis GTM
Tom Regan is the founding SDR leader at Apollo.io, where he helped scale the company from $800K to $50M ARR during the seed round. He is a GTM Advisor at Amplemarket and the founder of Artemis GTM, a consultancy that helps B2B SaaS companies ($1M-$50M ARR) find and fix pipeline revenue leaks. He created the Revenue Leak Framework after auditing 127+ companies and finding that the median B2B SaaS company leaks $1.6M in annual revenue from five systematic pipeline failures.
Apollo.io: Building the SDR Engine From Zero
Tom joined Apollo.io as the founding SDR leader during the seed round. At a time when the company was doing $800K in ARR, he built and scaled the sales development function that became a core growth engine as Apollo grew to $50M ARR.
During his time at Apollo, Tom sold $1.18M ARR in FY2021 (132% attainment) and $1.27M ARR in FY2019 (152% attainment). He developed the first career progression path for SDRs at Apollo, establishing the playbooks and processes that the team continued to use through hypergrowth.
The experience of building a go-to-market engine inside one of the fastest-growing sales tech companies in the market shaped everything that came next. Tom saw firsthand what works when you're scaling outbound at speed, and what breaks when you try to grow without the right foundation.
Amplemarket: GTM Advisor
Tom serves as a GTM Advisor at Amplemarket, the AI-native multichannel sales engagement platform. He works closely with the product team and Amplemarket's AI copilot, Duo, to refine B2B automated outbound strategy.
This role gives Tom direct access to the cutting edge of sales AI: data enrichment waterfall technology, AI-written personalized outreach, and multichannel sequence optimization across email, LinkedIn, and phone. His recommendations for tools like Amplemarket are informed by hands-on advisory work, not just product demos.
Artemis GTM: Finding and Fixing Revenue Leaks
Artemis GTM exists because Tom kept seeing the same problems in company after company. Startups with good products and decent traffic were leaving hundreds of thousands of dollars on the table because of five systematic failures in their pipeline.
He built the Flash Audit tool to diagnose these leaks in under two minutes and developed the Revenue Leak Framework as a structured methodology for prioritizing fixes by revenue impact.
After auditing 127+ B2B SaaS companies between $1M and $50M ARR, Artemis GTM has identified that the median company leaks $1.6M in annual revenue from unidentified website traffic, slow lead response times, data decay, coaching gaps, and CRM pipeline inaccuracy.
Artemis GTM is an independent consultancy. It is not affiliated with BrandJet AI's Artemis MCP, Artemis Analytics (crypto), ArtemisGTM.com, or the useartemis.co sales tool.
